No Drawing.

1 '0 all whom it may concern Be it known that I, SAMUEL EDWARDS, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, oitizen of the U cited States, have invented or discovered certain new and useful Improveinents in Fluxes for Coating Metal Articles, 01 which inqgrmements the following is a specification.

Wliile there has been comparatively little diiliculty exoerie nced in coating metal sheets and other articles with variety of metals as tin, zinc, etc, and alloys of metals as nine and lead, tin and lead, etc, but it has been found impracticable to coat metal articles, sheets, etc., with a uniformly adherent coatof pure lead, by immersing the sheets or other articles in a molten bath of lead. The lack of commercially;practicable results is due to the ditliculty of properly flaring the surfaces at the relative low tern peratur of a molten pure lead. The object of the invention described herein is to n-ovide a suitable flux and to so apply the flux that the lead will firmly adhere to the The invention is descrlbed and surfaces to be coated. hereinafter more fully claimed.

In the practice of my invention, I take a suitable quantity of hydrochloric-acid, say one hundred pounds, and add thereto about two and one half per cent. of zinc which will dissolve therein. This mixture forms approximately one half of my improved flux. The other half consists of one Specification of Letters Zatent.

hundred pounds of hydrochloric acid to which is added one per cent. (1%) of aluminum and one half of one per cent. of sa l an'inioniac. After these solutions have been formed they are mixed together. The arti-,'

formed by adding zinc, aluminum and sat ammoniac to hydrochloric acid in .substan tially the proportions stated.

ing a flux for coating with lead, which consists in dissolving zinc in suitable quantity hydrochloric acid, mixing aluminum and sal arninoniac in a. substantially equal quar tity of hydrochloric acid, and then mixing the two solutions. I

In testimony whereof, I have hereunto set my hand.
